在cmd上不显示输出

Question

I'm new to g++ compilers on windows. I installed a g++ compiler(MinGW). I imported a c++ file on python using MinGW in cmd in administrator mode.

Python code :

import sys, os
def main(argv):
    if '-i' in argv[0]:
        run(argv[1])
def run(a): 
    os.system('g++ ' + a+'.cpp' + ' -o  ' + a + '.exe')
    os.system(a + '.exe')
if __name__ =='__main__':       
    main(sys.argv[1:])

The C++ code :

#include<iostream>
using namespace std;
int main()
{
    int a,r,b=0;
    cout<<"enter a number : ";
    cin>>a;
    int t=a;
    while(a)
    {
        r=a%10;
        b=b*10+r;
        a/=10;
    }
    if(t==b)
        cout<<"\n Palindrome";
    else
        cout<<"\n Not a palindrome";
}

My cmd works :

where D:\\Program Files\\Python and D:\\Program Files\\MinGW\\bin are the folders containing Python and MinGW .exe files respectively.

No output is displayed here. According to the code, The output should be :

enter a number : 7676

Not a palindrome

or

enter a number : 767

Palindrome

When I execute the same code in Ubuntu terminal, I got the expected output whereas in cmd it's not. Kindly help me to get the desired output...
